Abstract
The excessive use of chemical pesticides in controlling plant pests and diseases has caused various negative impacts on the environment and human health. Plant Growth Promoting Rhizobacteria (PGPR) are a group of rhizosphere bacteria that have the ability to stimulate plant growth while controlling plant pathogens through biotechnological mechanisms. This study aims to examine the application of PGPR biotechnology as an environmentally friendly biocontrol agent for plant pests and diseases through the Systematic Literature Review (SLR) method. Secondary data were collected from 14 international and national journals indexed by Scopus for the period 2020-2025. A descriptive qualitative analysis was conducted to identify the working mechanism of PGPR, the types of pathogens that can be controlled, and the effectiveness of PGPR applications. The results of the study indicate that PGPR work through five main mechanisms: antibiosis, competition for nutrients and space, production of lytic enzymes, induction of systemic resistance (ISR), and quorum sensing interference. The genera Bacillus and Pseudomonas are the most widely studied PGPR with the ability to control fungal pathogens such as Fusarium, Rhizoctonia, Pythium, and bacterial pathogens such as Ralstonia and Xanthomonas. The effectiveness of PGPR in suppressing plant diseases ranges from 54-80%, with plant growth increases of up to 35%. Application of PGPR consortia showed better results than single isolates. This study concludes that PGPR biotechnology has great potential as an alternative to chemical pesticides for sustainable agriculture.
